ATTORNEY United States Patent 6 TOILET DEODORIZER James R. Herriott, Alamo, Calif.

Application July 14, 1953, Serial No. 367,920

4 Claims. (Cl. 4-213) The present invention relates to improvements in a toilet deodorizer, and its principal object is to provide a deodorizer of the character described that is simple in construction, fits nicely into a standard toilet set-up, is easy to install, and is economic and eflicient in operation.

More particularly, it is proposed to provide a deodorizing cabinet which may be readily accommodated underneath the tank commonly arranged in the rear of the toilet bowl, and is shaped to substantially merge into the outline of the tank so as to be relatively inconspicuous and unnoticeable.

It is further proposed to provide a deodorizing cabinet which may be secured with respect to the tank by a mere bracing or clamping action, without the aid of any screws or other fastening means.

It is additionally proposed to provide a securing means for the cabinet which may be readily modified for tanks of different heights above the floor level.

Again, it is proposed to provide a deodorizing cabinet equipped with a special deodorizing magazine removably secured thereto and convenient of access for replacement purposes.

It is a further object of my invention to provide a special suction conduit with a suction nozzle which may be readily fitted over the side edge of the toilet bowl and which is flattened to fit between the toilet bowl and the standard toilet seat.

And finally, it is proposed to provide a cabinet having a blower mounted therein, with electrical connections for operating the same and conduit connections whereby air is wtihdrawn from the toilet bowl through the suction conduit, and is made to pass through the deodorizing magazine for final discharge into the atmosphere in purified. condition.

Further objects and advantages of my invention will appear as the specification procee,ds,,and the new and useful features of my deodorized will be fully defined in thej'claims' attachedhereto. i i

The preferred form of my invention is illustrated in the accompanying drawing, forming part of this application, in which:

Figure 1 shows a side view of my deodorizer, the outlines of the toilet bowl and the standard flushing tank being shown in dotted lines;

Figure 2, a plan view of my deodorizer, with the bowl and the tank shown in dotted lines;

Figure 3, a horizontal section through my cabinet, taken along line 3-3 of Figure 1; and

Figure 4, a vertical section through the nozzle of my suction conduit taken along line 4-4 of Figure 2.

While I have shown only the preferred form of my invention, it should be understood that various changes or modifications may be made within the scope of the claims hereto attached, without departing from the spirit of the invention.

Referring to the drawing in detail, my deodorizer is shown in connection with a standard installation of a ICC toilet bowl 5 and a flushing tank 6 mounted rearwardly thereof, both being shown in dotted lines.

In accordance with standard practice, the bottom plane 7 of the tank is shown as being in alinement with the top plane 8 of the bowl. The toilet seat and toilet cover conventionally provided above the toilet bowl are not shown, it being understood that in common practice, the seat is mounted on the bowl in slightly spaced relation, and that both the seat and the cover are hinged for upward swinging movement into inactive positions.

The bowl is provided, in accordance with standard practice, wtih a rearwardly projecting flange 9, the upper surface of which lies in the plane of the upper surface of the bowl and which extends partly underneath the tank and is commonly bolted thereto.

My deodorizer comprises, in its principal features, a cabniet 10 having a magazine 11 removably secured upon a side thereof, a suction conduit 12 terminating in a nozzle 13 adapted for securing upon the side of the toilet bowl, a blower 14 mounted in the cabinet, and connecting means causing the blower to draw on the space inside the bowl and to discharge through the magazine into the atmosphere.

The cabinet 19 is preferably made rectangular in form to present parallel front and rear walls 15 and 16, a flat top 17, and an open side indicated at 18. The cabinet is intended to fit underneath the toilet tank, and may be of a depth between front and rear walls to correspond substantially to the depth of the toilet tank, although it is shown in the drawing somewhat narrower to bring out the positioning with respect to the toilet tank more clearly.

The cabinet is supported by a post 19 comprising a base 20, a shaft 21 threaded thereinto and a rod 22 threaded into the shaft, as at 23. The overall length of the post should be such, with respect to the height of the tank above the floor level that it brings the top of the cabinet close to the bottom of the tank when the cabinet is placed in position, and that it allows the top of the cabinet to be clamped upon the bottom of the tank by a mere turning movement of the base.

Thus, the cabinet is held in position by the clamping or bracing action of the post, without the aid of any screws or bolts or other fastening means.

For variations in the heights of different. toilet tanks in excess of the capacity of the thread 23, a number of shafts 21 of different lengths may be provided, for selection of the proper one at the point of installation.

The top of the cabinet may be formed with a suitable indentation, such as shown at 24, to clear any opposing obstacle to the positioning of the cabinet in the manner described, as forinstance, the flange 9 extending partly underneath the tank in some installations.

It is the intention to make the cabinet, with the magazine, of a width to correspond substantially to one-half the width of the tank, as shown.

The cabinet has the blower 14 mounted upon the rear face of its front wall, with a motor 25 placed rearwardly of the blower for driving the latter. The motor is suitably connected into an electrical circuit controllable by a switch button 26 mounted upon the front wall of the cabinet.

The blower intake 27 connects through the flexible conduit 12 with the nozzle 13 adapted for hooking over the side edge of the toilet bowl. The nozzle comprises a rigid conduit 28 forming an extension of the flexible conduit, a flattened wing 29 rising from the top of the conduit 28 and a flattened wing 39 turning inwardly from the top of the first wing and adapted to lie on top of the edge of the bowl, the wings being contoured to fit the contour of the bowl and having relatively narrow slots 31 extending through the widths thereof.

The top wing is sufliciently narrow for accommodation between the bowl edge and the toilet seat (not shown), and is held in position by a pair of hooks 32 fitting over the inner edge of the bowl.

The blower 14- discharges sidewise toward the open side of the cabinet through an exhaust pipe 33, the end of the latter pipe coming flush with the edges of the cabinet.

The magazine 11 is of the same cross-section as the cabinet and is removably clamped upon the open side of the cabinet to form a closure for the same. The clamping means comprises a plurality of flanges 34 adapted to clampingly engage upon the front and rear walls of the cabinet as the magazine is positioned.

The magazine is filled with a suitable deodorizing agent, such as pellets of activated carbon, and has an intake pipe 35 telescoping over the exhaust pipe 33 of the blower when the magazine is inserted.

The opposing or free face of the magazine is formed with a series of perforations 36 along the upper edge thereof, so as to cause air discharged from the blower to pass through the bulk of the activated carbon before it is discharged into the atmosphere.

The intake 35 of the magazine and the outlet perforations 36 are preferably covered with wire netting, as indicated at 37 and 38, respectively.

In. use, the cabinet may be readily installed by placing the same underneath the available side of the toilet tank and by turning the base until the upper face of the cabinet clamps against the underface of the tank.

The magazine may be easily applied by placing the same upon the open side of the cabinet, and is held in place by the flanges 34. The nozzle 13 is then lowered upon the edge of the bowl and is held automatically by hooks 32. This completes the installation, except for establishing electrical connections for the motor which merely means plugging into a wall socket.

Upon closing of the switch 26, the blower will draw air from the bowl through the nozzle 13 and the flexible conduit 12, and will discharge the same into the deodorizing magazine for final exhaust of the purified air into the atmosphere.

The magazine may be readily replaced from time to time, as needed, by a new one.
